Round-trip efficiency is not very important for a backup storage medium when the marginal cost to produce is zero.
Other considerations drive choices, then, e.g. capex, transportability, usefulness for other processes.
- _hypx 4y agoAnd once you realize that nearly all renewable energy production has a marginal cost of zero, then it quickly becomes the overwhelmingly best idea for energy storage.
